Ceramic compound bonding agent bonded to metal

Abstract

The invention discloses a ceramic compound bonding agent bonded to metal. The agent is characterized by comprising substances in parts by weight as follows: 21-48 parts of ceramic powder, 10-34 parts of tin powder, 11-25 parts of iron ore, 5-13.8 parts of boron oxide, 1-8 parts of calcium oxide, 12-34 parts of calcined kaolin, 35-74 parts of algeldrate, 13.8-41.6 parts of active silica micro powder, 11-21 parts of raw kaolin, 30-45 parts of gravels, 11-35 parts of bronze powder, 4-18 parts of boron carbide and 13.6-41.8 parts of calcium stannate. The agent keeps the characteristics of the good sharpness and the good self-sharpening property of a ceramic bonding agent and has the advantages of the high rigidity and the good shape retention property of a metal bonding agent, so that the comprehensive processing efficiency is improved.

Description

technical field [0001] The invention relates to a ceramic composite binder combined with metal. Background technique [0002] Grinding wheel is the main tool for grinding, which is a porous object composed of abrasive and bonding agent. Diamond abrasives are used as raw materials, and metal powder, resin powder, and ceramics are used as binders respectively. The circular bonded abrasive with a through hole in the center is called a diamond grinding wheel. Due to the characteristics of diamond abrasives (high hardness, high compressive strength, and good wear resistance), diamond abrasives have become ideal tools for grinding hard and brittle materials and cemented carbide in grinding processing, and are widely used in processing low Metal and non-metal hard and brittle materials with iron content. [0003] With the development of science and technology, CNC ultra-precision grinding machines, high-speed and high-precision crankshaft grinding machines and camshaft grinding m...

Problems solved by technology

[0004] Although the traditional resin diamond grinding wheel has good sharpness and good self-sharpening, it has low heat resistance, insufficient wear resistance and short dressing gap, which affects production efficiency; Although the diamond grinding wheel has good sharpness, it has poor wear resistance and is difficult to trim; although the metal diamond grinding wheel has good shape retention, its self-sharpening is not good, and it cannot meet the needs of continuous processing.

[0005]The excellent sharpness, self-sharpening and super wear resistance of diamond grinding wheel are the key to fully improve the processing efficiency of CNC grinding machine; The key factor for the performance of diamond grinding wheels, the traditional single bond can no longer meet the performance needs of diamond grinding wheels for CNC grinding machines that require high processing efficiency
